1670 TWL4030 family chips. Most of these resources are regulators,
1671 which have a separate driver; some are control signals, such
1672 as clock request handshaking.

1674 This driver uses board-specific data to initialize the resources
1675 and load scripts controlling which resources are switched off/on
1676 or reset when a sleep, wakeup or warm reset event occurs.
